After initial attachment your Qlixbi stays with you and your regulator.
Your Qlixbi clicks in to the cylinder. No spanner, no wrench required. Your Qlixbi rotates through 360o so you can position the regulator at any position.
Lift the red lever up to open the gas flow. Use the regulator to manage the gas flow. That's it! You're ready to weld!
Push the red lever down to turn off the gas flow.
Check the red lever is firmly in the down position. To uncouple your Qlixbi, grip the side and lift up and out of the cylinder.
